Automatic Clamp for Wide Concrete Blocks AT-SS (600 kg WLL)

Maximise efficiency and safety on your site with the Automatic Clamp for Wide Concrete Blocks AT-SS, available at Craneplex. Engineered specifically for the secure handling of heavy materials, this heavy-duty lifting clamp is the perfect solution for safely lifting, moving, and positioning concrete blocks with parallel side surfaces.

With a highly versatile gripping range and an impressive Working Load Limit (WLL) of 600 kg, this clamp is an essential tool for construction, manufacturing, and logistical operations. Manufactured in the EU to the highest safety and engineering standards, the AT-SS clamp is designed to save time and significantly reduce manual handling risks on site.

Operational Design & Core Advantages

To support highly efficient and secure site operations, the AT-SS clamp features several intelligent, labour-saving design elements:

• Independent Operation (Labour Saving): Equipped with an intelligent automatic lock and latching mechanism. This allows the clamping jaws to alternately close and open during lifting and lowering cycles, enabling the crane operator to control the load entirely independently without requiring extra manual assistance on the ground.
• Adjustable Gripping Range: Highly adaptable, the clamp is easily adjusted to accommodate load widths ranging from 50 mm up to 600 mm. The width of the body is modified and securely locked in place using a robust central pin and cotter pin system.
• Damage-Free Handling: The gripping jaws and support feet feature premium, soft linings with a high coefficient of friction. This ensures a firm, slip-free hold on the load whilst completely protecting the surface of your concrete blocks from scratches or impact damage.
• Safe Transport & Storage: Features a built-in locking mechanism that securely holds the gripper in the open position, ensuring safe transit, secure storage, and ease of positioning prior to your next lift.
